👉 In physics, a copatron is a type of particle accelerator that can accelerate charged particles to very high speeds. These particles are called protons and neutrons, and they are used in various experiments such as neutron capture reactions, proton-proton collisions, and other particle physics processes. Copartners are often described as "protons" because they contain the same number of protons (2) as electrons (1), making them a type of elementary particle. They can be accelerated to very high
